摘要:

In this paper, we study a boundary value problem of nonlinear fractional dif-ferential equations of order q (1 < q  2) with non-separated integral boundary conditions. Some new existence and uniqueness results are obtained by using some standard fixed point theorems and Leray-Schauder degree theory. Some illustrative examples are also presented. We extend previous results even in the integer case q = 2.

关键词: fractional differential equations, non-separated integral boundary condi-tions, contraction principle, Krasnoselskii´s fixed point theorem, Leray-Schauder degree
